在金融危机的汹汹来势中,马克思批判资本主义的巨著《资本论》再次进入欧洲人的视野。既然欧洲政要和民众都在读《资本论》,我们也有必要重温这部巨著,在重新解读中真正认识资本主义的历史性,正确看待资本的两重性等问题,结合实际推动马克思主义中国化的历史进程。 相似文献

抗战初期,晋察冀边区为解决财政困难、支持持久抗战,决定发行救国公债。边区政府制订了正确的政策,广大民众踊跃认购,是救国公债成功发行的主要原因。公债的成功发行,解决了边区财政困难,支持了持久抗战,为以后发行公债(国债)提供了借鉴。 相似文献

A company wishes to estimate or predict its financial exposure in a reporting period of length T (typically one quarter) because of warranty claims. We propose a fairly general random measure model which allows computation of the Laplace transform of the total claim made against the company in the reporting interval due to warranty claims. When specialized to a Poisson process of both sales and warranty claims, statistical estimation of relevant quantities is possible. The methodology is illustrated by analyzing automobile sales and warranty claims data from a large car manufacturer for a single car model and model year. © 2008 Wiley Periodicals, Inc.

In this article, we consider a classic dynamic inventory control problem of a self‐financing retailer who periodically replenishes its stock from a supplier and sells it to the market. The replenishment decisions of the retailer are constrained by cash flow, which is updated periodically following purchasing and sales in each period. Excess demand in each period is lost when insufficient inventory is in stock. The retailer's objective is to maximize its expected terminal wealth at the end of the planning horizon. We characterize the optimal inventory control policy and present a simple algorithm for computing the optimal policies for each period. Conditions are identified under which the optimal control policies are identical across periods. We also present comparative statics results on the optimal control policy. © 2008 Wiley Periodicals, Inc. Naval Research Logistics 2008 相似文献

In financial engineering, sensitivities of derivative prices (also known as the Greeks) are important quantities in risk management, and stochastic gradient estimation methods are used to estimate them given the market parameters. In practice, the surface (function) of the Greeks with respect to the underlying parameters is much more desired, because it can be used in real‐time risk management. In this paper, we consider derivatives with multiple underlying assets, and propose three stochastic kriging‐based methods, the element‐by‐element, the importance mapping, and the Cholesky decomposition, to fit the surface of the gamma matrix that can fulfill the time constraint and the precision requirement in real‐time risk management. Numerical experiments are provided to illustrate the effectiveness of the proposed methods. 相似文献

Derivatives (or gradients) are important for both sensitivity analysis and optimization, and in simulation models, these can often be estimated efficiently using various methods other than brute‐force finite differences. This article briefly summarizes the main approaches and discusses areas in which the approaches can most fruitfully be applied: queueing, inventory, and finance. In finance, the focus is on derivatives of another sort. © 2008 Wiley Periodicals, Inc. Naval Research Logistics, 2008 相似文献

An analysis of the security vetting files of 19 employees within a South African national department who had been found guilty of financial misconduct in the last five years uncovered that the existing security vetting processes did not detect the financial misconduct of which these employees have been found guilty. This research sets out to establish whether security vetting can be extended to include the detection of financial misconduct within the department and, if so, how. Moreover, if security vetting can indeed be so extended, can it possibly enhance the management of fraud risk across all South African public sector departments? Qualitative interviews were conducted with 27 employees who are key to fraud risk management and security vetting within the researched department. During the interviews, the following five themes emerged: (1) the reasons why employees commit financial misconduct; (2) why it is not detected by the security vetting process; (3) the potential alignment of the security vetting process to facilitate the detection of financial misconduct; (4) the following through on security vetting findings; and (5) sharing these findings with the internal audit and risk management functions within state departments. These themes were probed and are reported on, establishing firstly that security vetting can indeed be extended to include the detection of financial misconduct within the researched department, and secondly that it can enhance the management of fraud risk across all South African public sector departments, given the specific mandate of the State Security Agency (SSA) and the national security vetting strategy. 相似文献

In recent years, there have been several changes in the weapon‐system acquisition market which have the potential to negatively impact the financial condition of defense contractors. This study evaluates the financial health of defense firms vis‐a‐vis nondefense firms using a fiscal distress identification model developed by E.I. Altman. We conclude that the financial condition of defense firms has deteriorated but the deterioration is the same as experienced by nondefense firms. 相似文献
